Detailed ways

The present invention will be further described below according to the accompanying drawings and embodiments.

As shown in Figure 1, Figure 2 and Figure 3 of the accompanying drawings, a self-locking vehicle arrester in a tank includes two tracks 10 laid in parallel on the lower part of the cage, and is characterized in that: on the two tracks 10 There are two groups of symmetrical arc grooves, the center distance of the two groups of arc grooves is equal to the center distance of the two groups of wheels 1, and the arc grooves include the grooved car-blocking rails fixed on the track 10 2 and the groove rail support plate 9, the groove rail 2 is in direct contact with the wheel 1, and the space between the groove rail support plate 9 and the groove rail 2 is movably installed with an arc The self-locking anti-vehicle body 3, a synchronous beam I7 is installed between the two self-locking anti-vehicle bodies 3 of a group of arc grooves, and the two ends and the middle of the self-locking anti-vehicle body 3 are installed with The roller 3-1 and the synchronous beam I7 of the vehicle blocking body are connected to the middle roller 3-1. A reverse sheave 6 is installed between the synchronous beam I7 of the car-blocking body and the synchronous beam II7′ of another set of arc-shaped grooves, and there are two steel wire ropes 15 with opposite winding directions on the reverse sheave 6. One end of the wire rope 15 is fixed on the reverse sheave 6, and the other ends of the two wire ropes 15 are respectively fixed to the synchronous beam I7 of the car-blocking body and the synchronous beam II7' of the car-blocking body. The same root of the reverse sheave 6 Driven sprocket 14 is housed on the rotating shaft, and driven sprocket 14 is connected driving sprocket 12 to form chain drive pair by chain 13, and retractable gear 8 is housed on the same root rotating shaft of described driving sprocket 12, and described two tracks Outer oil cylinder 4 is housed between 10, and the driving rack 11 that meshes with described pull-in gear 8 is housed on the piston rod of outer oil cylinder 4.
